Even if pictures get posted and show its det that has killed the engine, that det could still have been caused by the FPR ultimately.
Could be a case of:
Engine has no det
FPR pipe comes off, engine goes lean and dets for a bit
The det nips the ringlands up on the rings, but all still seems ok from outside
The rings allow oil past
The oil lowers the det threshold of the charge in the chamber
Engine dets
Personally that seems a little unlikely to me, but it is potentially "possible" so I dont think we will EVER know for sure what killed it.
What we do know, is if the map only goes to 1.87 bar, despite the map sensor being able to go to just over 2 bar, and the car running just over 2 bar, then whoever decided the map was appropriate for that, made a mistake in doing so, wether it killed the engine or not, it still sounds like it was just fundamentally not correct.
